Measuring 0.4375 inches (7\/16 inches) in diameter with a 140-degree drill point angle, this bit features a TiAlN coating, helical fluting, and X-thinning web geometry to reduce thrust and improve chip evacuation. With an overall length of 6.3000 inches and a flute length of 3.7010 inches, the MVS Series construction supports deeper reach than standard-length tooling. Coolant-through capability makes it suitable for high-speed, high-precision operations in production environments. Licensed machinists, tool-and-die technicians, and CNC operators are the primary installers and users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for cross hole drilling, stack drilling, and standard through-hole drilling operations across a broad range of workpiece materials. Primary applications target steel, stainless steel, structural steel, tempered steel, hardened steel, and carbon steel. Secondary material compatibility extends to aluminum, aluminum alloy, brass, bronze, high-strength bronze, copper, cast iron, iron, and superalloys including titanium. The 5xD flute-to-diameter ratio and right-hand spiral cutting direction make it well-suited for CNC machining centers and production drilling fixtures requiring consistent hole quality and tight tolerances.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide construction with TiAlN coating for heat resistance and extended tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle with X-thinning reduces entry thrust and improves centering accuracy\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed drilling and efficient chip removal in deep-hole applications\u003c\/li\u003e\n  \u003cli\u003e6.3000-inch overall length with 3.7010-inch flute length provides extended reach compared to jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eHelical, right-hand flute geometry with parallel web configuration for consistent chip flow\u003c\/li\u003e\n  \u003cli\u003eMaximum drilling depth of 2.2670 inches (57.58 mm) within the 5xD design envelope\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers, drill presses, and production drilling fixtures that accept a 0.472-inch cylindrical shank.

Ensure the machine spindle and tool holder are powered down and locked out before mounting or removing the bit. Verify that the tool holder bore matches the 0.472-inch shank diameter and that the bit is secured to the full recommended shank engagement depth to prevent runout. Coolant-through tooling requires a compatible spindle coolant delivery system to be active during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 11.11 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (Decimal Inch)\u003c\/strong\u003e: 6.3000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (mm)\u003c\/strong\u003e: 160.02 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length (Decimal Inch)\u003c\/strong\u003e: 3.7010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length (mm)\u003c\/strong\u003e: 94.01 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal Inch)\u003c\/strong\u003e: 0.472 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 12.0000 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length (Decimal Inch)\u003c\/strong\u003e: 2.4410 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length (mm)\u003c\/strong\u003e: 62.000 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth (Decimal Inch)\u003c\/strong\u003e: 2.2670 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth (mm)\u003c\/strong\u003e: 57.58 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length (Decimal Inch)\u003c\/strong\u003e: 0.0800 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length (mm)\u003c\/strong\u003e: 2.03 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: X-Thinning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MVS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Cross Hole, Drilling, Stack Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.37 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MITSUBISHI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 663074\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITSUBISHI ELECTRIC","offers":[{"title":"Default Title","offer_id":51691139039538,"sku":"663074","price":443.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c379bcb8d08cb8569efb7441d13f2935_1c96b405-031c-4817-8ba5-cc9345fd3050.jpg?v=1788280734","url":"https:\/\/voomisupply.com\/products\/mitsubishi-663074-extra-length-carbide-drill-bit-7-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
